How to Whip Egg Whites to Stiff Peaks
The transformation of egg whites from a thin, translucent liquid into a dense, cloud-like foam is the foundation for soufflés, meringues, and light cakes. Mastering this process requires watching for the specific resistance of the foam, rather than relying on a clock.
Control the environment
Egg whites whip faster and reach a higher volume when they are at room temperature. Ensure your bowl and whisk are free of any oil or grease, as even a microscopic amount will prevent the whites from foaming.

- 1 pinchcream of tartar (optional, for stability)
The Stiff Peak Test
When you pull the whisk out of the foam, the peak should stand straight up without curving or drooping. If it flops over, you have soft peaks; if the foam looks grainy or curdled, you have over-beaten it.
The method.
Separate the eggs
Crack each egg into a small bowl first before adding the white to your large mixing bowl. This ensures that if a yolk breaks, you do not ruin the entire batch.
Begin at low speed
Start beating the whites slowly until they become foamy and opaque, similar to the texture of sea foam. Add the cream of tartar at this stage if you are using it.
Increase to medium-high
Once the whites are bubbly, increase the speed. The air bubbles will shrink and the mixture will begin to hold faint lines from the whisk.
Verify the peaks
Stop the mixer frequently to check the texture. Lift the whisk vertically. If the white stands upright like a sharp mountain range, stop immediately.
Other turns to take.
Sweet Meringue
Gradually beat in superfine sugar once the whites reach soft peaks; this adds weight and creates a glossy finish.
When it doesn't go to plan.
Wipe your bowl with a drop of lemon juice on a paper towel before starting to ensure no hidden grease remains.
Do not over-beat; if the mixture looks dry or like cotton wool, the protein bonds have snapped and you must start over.
If you accidentally get yolk in the white, use an empty eggshell to scoop it out; it acts like a magnet for the fat.
The ones that keep coming up.
Can I use plastic bowls?
Avoid them. Plastic is porous and often retains trace amounts of fat from previous uses, which can prevent the whites from ever reaching their full volume.
Why did my whites turn watery?
This usually means you beat them too long and the structure collapsed, or there was a tiny amount of yolk contamination.
